STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH

N/A.

BACKGROUND

Helmets are generally worn to provide a buffer between a user's head and an object that comes into contact with the helmet. While helmets are used during various activities, such as during construction, mining, etc., a large proportion of manufactured helmets are used for sporting activities. For example, bicycle helmets are worn by cyclists, which when worn appropriately under certain circumstances can help to provide a buffer in the event of a fall or crash. Generally, such helmets are secured in place by a strap system consisting of straps attached to left and right sides of the helmet, respectively, and each including mating latch features that can be secured together under the wearer's chin. In the event of a fall or crash, the localized attachment points between the straps and the helmet can experience significant retention loads. It would be desirable to have systems and methods for helmet constructions that allow for improved strap retention load distribution.

DETAILED DESCRIPTION

Bicycle helmets can help provide a buffer during certain activities. These helmets often include a generally hemispherical body, made of one or more internal support structures and surrounding foam material, with a cavity that receives the head of the user. Straps are coupled to the hemispherical body to be secured around the user's chin, e.g., via a clip. For example, each strap may be wrapped around one of the support structures and secured to itself. However, this engagement adds extra steps to the assembly process prior to encapsulating the support structures in the foam material, does not allow for strap replacement, and continued movement of the straps, e.g., when securing and releasing the straps or during falls or crashes, may affect the foam material around where the straps emerge. In another example, each strap may be coupled to a floating structure embedded within the foam material. However, pulling of the straps, for example during a fall, a crash, or when securing the helmet, can cause significant localized forces adjacent the floating structure. On the other hand, enhanced embodiments described herein provide a helmet including a body having a foam material that defines one or more vents, one or more support structures embedded in the foam material and encircling one or more of the vents, and strap hangers that are coupled to the support structure(s) and accessible from outside the body. Such embodiments permit straps to be tied into the helmet post-assembly and distribute forces from pulled straps throughout the support structures of the helmet rather than localized areas within the foam body.

For example, FIG. 1 shows a front isometric view of a helmet 100 according to some example embodiments. The helmet 100 can define a front end 102, a rear end 104, and lateral ends 106, 108. The helmet 100 can include a cage 110, a body 112 that partially encapsulates the cage 110, and a shell 114 that is positioned on top of and is coupled to the body 112. The helmet 100 also includes one or more vents 116 defined by the cage 110, the body 112, and/or the shell 114, each of which extends longitudinally between the rear end 104 of the helmet 100 and the front end 102 of the helmet 100. As shown, one or more of the vents 116, may not extend an entire length of the helmet 100 from the rear end 104 to the front end 102 but, rather, may only extend a portion of the length of the helmet 100. Additionally, the helmet 100 can include one or more rear vents 117, defined by the cage 110, the body 112, and/or the shell 114, located at the rear end 104 of the helmet 100.

Generally, the cage 110 can form a structural support for the helmet 100. For example, in some embodiments, portions of the cage 110 can enclose or encircle the vents 116, 117 and/or portions of the cage 110 can extend through one or more vents 116, 117. As a result, the cage 110 can provide sufficient structural integrity while still allowing the vents 116, 117 to decrease the bulkiness and weight of the helmet 100, and provide airflow paths, allowing air to flow into and out of the vents 116, 117 to facilitate sweat evaporation from the wearer's head.

FIG. 2 shows a front isometric view of the cage 110 in an assembled configuration, while FIG. 3 shows a rear isometric view of the cage 110, also in an assembled configuration. As shown, the cage 110 can define a front end 118, a rear end 120, and opposing lateral ends 122, 124. The cage 110 can include rims 126, 128, one or more longitudinal beams 130, one or more transverse beams 132, plates 134, 136, and joists 138, 140. In some embodiments, the rims 126, 128, the longitudinal beams 130, the transverse beams 132, and the joists 138, 140 can each be formed of a single filament of a flexible material or a braided filament of flexible material (e.g., braided aramid). Furthermore, one or more strap hangers 142, 144 can be coupled to the cage 110, as further described below.

As shown in FIGS. 2 and 3 , the rim 126 (e.g., a lower rim) extends around the lower periphery of the cage 110. Situated above the rim 126 is the rim 128 (e.g., an upper rim), which also extends around the lower periphery of the cage 110. Additionally, in some embodiments, one or more (e.g., each) longitudinal beam 130 extends in a longitudinal direction between the rear end 120 of the cage 110 and the front end 118 of the cage 110. For example, as shown in FIGS. 2 and 3 , the rim 128 can be coupled to one or more (e.g., each) of the longitudinal beams 130 at coupling locations 146 adjacent the front end 118 of the cage 110 and the rear end 120 of the cage 110. Furthermore, as shown in FIGS. 2 and 3 , the transverse beams 132 can extend from the rim 128 on the first lateral end 122 to the rim 128 on the second lateral end 124. Also, in some embodiments, and as shown in FIGS. 2 and 3 , one or more (e.g., each) of the transverse beams 132 can be coupled to one or more (e.g., each) of the longitudinal beams 130 at specified coupling locations 146.

Generally, the longitudinal beams 130 and/or the rims 126, 128 can be spaced apart such that the cage 110, and more specifically, the longitudinal beams 130 and/or the rims 126, 128 help define the vents 116. The transverse beams 132 can be spaced apart and positioned relative to the longitudinal beams 130 and/or the rims 126, 128 such that the cage 110, including the transverse beams 132 and/or the rims 126, 128, and some portions of the longitudinal beams 130, can form a structural support that encircles the vents 116. At the rear end 104, the rims 126, 128, the longitudinal beams 130, and the joists 140 can be spaced apart and positioned relative to each other such that the cage 110 and, more specifically, the rims 126, 128, the longitudinal beams 130, and the joists 140 can help define and encircle the rear vents 117. Furthermore, the transverse beams 132 can be spaced apart and positioned relative to the longitudinal beams 130 and/or the rims 126, 128 such that the cage 110, including some portions of the longitudinal beams 130, can extend through the vents 116 and/or the rear vents 117.

Referring still to FIGS. 2 and 3 , in some embodiments, the plates 134, 136 can help anchor the transverse beams 132 to the rim 128. For example, the plates 134, 136 can be situated along opposing ends 122, 124 of the cage 110 and are coupled to one or more of (e.g., each of) the transverse beams 132, the rims 126, 128, and/or the joists 138, 140. More specifically, the plate 134 is situated on the lateral end 122 of the cage 110, and a first lateral end of each of the transverse beams 132, a portion of the rim 128, and upper portions of the joists 138, 140 are each coupled to the plate 134. Furthermore, in some embodiments, the plate 134 can comprise multiple layers that are coupled to the beams 132, the rim 128, and/or the joists 138, 140 by being sandwiched around, and, e.g., coupled together around, either side of the beams 132, the rim 128, and the joists 138, 140. That is, the plate 134 can include a set of plates comprising a first or outer plate coupled to an outer surface of the cage 110 and a second or inner plate coupled to an inner surface of the cage 110.

Additionally, the plate 136 is situated on the opposing lateral end 124 of the cage 110, and a second opposite lateral end of each of the transverse beams 132, a portion of the rim 128, and upper portions of the joists 138, 140 are each coupled to the plate 136. The plate 136 can also comprise multiple layers that are coupled to the beams 132, the rim 128, and/or the joists 138, 140 by being sandwiched around, and, e.g., coupled together around, either side of the beams 132, the rim 128, and the joists 138, 140. That is, the plate 136 can include a set of plates comprising a first or outer plate coupled to an outer surface of the cage 110 and a second or inner plate coupled to an inner surface of the cage 110.

As shown in FIGS. 2 and 3 , the strap hangers 142, 144 can be coupled to a support structure of the helmet 100, such as the cage 110. The strap hangers 142, 144 can receive straps (not shown) to form a strap system of the helmet 100 in order to secure the helmet 100 to a wearer's head. As described below and best shown in FIG. 7 , the strap hangers 142, 144 can be at least partially encapsulated by, or embedded within, the body 112, yet in some embodiments still accessible to permit strap installation and/or replacement after the helmet 100 is assembled.

In some embodiments, as shown in FIGS. 2 and 3 , the helmet 100 can include four strap hangers: a front strap hanger 142 and a rear strap hanger 144 configured to be coupled to the cage 110 along the first lateral end 122, and a front strap hanger 142 and a rear strap hanger 144 configured to be coupled to the cage 110 along the second lateral end 124. The front strap hangers 142 can be coupled to the cage 110 closer to the front end 118 of the cage 110 while the rear strap hangers 144 can be coupled to the cage 110 closer to the rear end 120 of the cage 110. However, in other embodiments, the helmet 100 can include two strap hangers, or other numbers of strap hangers, and/or the strap hangers may be coupled along other areas of the cage 110.

As shown in FIGS. 4 and 5 , each strap hanger 142, 144 can include at least one clip 148, support webbing 150, and a strap receiver 152. For example, the front strap hangers 142 can include two clips 148, support webbing 150, and a strap receiver 152, while the rear strap hangers 144 can include a single clip 148, support webbing 150, and a strap receiver 152. Additionally, each strap hanger 142, 144 can be made of a material, such as plastic, and the clip(s) 148, support webbing 150, and strap receiver 152 can be integrally formed in some embodiments, or separately formed and coupled together in some embodiments. Additionally, while the strap hangers 142, 144 may include different shapes and/or components in some embodiments, in other embodiments, all strap hangers 142, 144 may be identical.

As shown in FIGS. 2-6 , each clip 148 can include an outer curved section 154 and inner clip members 156 that collectively define a receiving area 158. The receiving area 158 can be sized to be substantially equal to a cross-section (such as a diameter) of a filament, e.g., of the rim 126 or another portion of the cage 110 (e.g., rim 128). As a result, the clip 148 can be clipped onto the rim 126 (or another portion of the cage 110) such that the rim 126 is received within the receiving area 158 via a press-fit engagement. In other words, the clip 148 can snap onto the cage 110. In some embodiments, however, the receiving area 158 can be larger than the filament and the clip 148 can instead hang on the cage 110 in a loose-fit engagement. In other example embodiments, the clip 148 can include a clamshell construction that hinges about the cage 110 and snap-fits together to capture a portion of the cage 110, therefore retaining the clip 148 to the cage 110. Accordingly, each strap hanger 142, 144 can be coupled to the cage 110 via the clip(s) 148. As a result of this engagement, load forces on a strap coupled to the strap hanger 142, 144 (such as load forces pulling the strap away from the helmet 100, e.g., caused by a fall or crash and/or when the straps are engaged to secure the helmet 100 to a wearer's head) can be distributed throughout the cage 110.

In some embodiments, the webbing 150 can extend at least between the clip 148 and the strap receiver 152. Furthermore, in some embodiments, the webbing 150 can extend outward away from the clip 148 and/or the strap receiver 152. For example, as shown in FIGS. 2, 3, and 4 , the rear strap hangers 144 can include webbing 150 with additional outwardly extending wings 160 that extend between the front end 118 and the rear end 120. Generally, the webbing 150 can connect the clip 148 to the strap receiver 152 so that the strap receiver 152 is spaced from the clip 148, allowing the strap receiver 152 to be accessible outside the body 112 while the clip 148, and its engagement with the cage 110, is encapsulated by the body 112, as shown in FIG. 7 . The webbing 150 can also provide additional structural support and surface area to help distribute load forces from the strap hanger 142, 144 within the body 112.

As noted above, the strap receivers 152 of the strap hangers 142, 144 can receive straps routed therethrough. For example, as shown in FIGS. 2-7 , each strap receiver 152 can include a lower opening 162 connected to an inner opening 164 to form an internal pathway 166 (shown in FIG. 6 ) through which a strap may be routed. In some embodiments, as shown in FIG. 6 , the internal pathway 166 can include a narrowed section 168 and/or internal protrusions 170. These features can provide friction against a strap while it is routed through the internal pathway 166, yet still allow for movement therethrough. However, in other embodiments, the internal pathway 166 may include a uniform cross-section without friction-causing features. As shown in FIG. 7 and as further described below, both the lower opening 162 and the inner opening 164 are accessible while the remainder of the strap hanger 142, 144 may be substantially encapsulated by the body 112. As a result, straps can be routed through the strap hangers 142, 144 after the helmet 100 is assembled or manufactured, permitting strap replacement or custom strap installation post-assembly or manufacturing of the helmet 100.

Accordingly, as described above, the strap hangers 142, 144, by being coupled to a structural support like the cage 110, can permit retention forces from the straps to be distributed across the helmet 100 rather than localized to strap attachment areas. While the strap hangers 142, 144 are shown and described herein as having the clips 148 that snap directly onto the cage 110, in some embodiments, the cage 110 can include one or more coupling mechanisms, such as receiving clips (not shown), to receive the strap hangers 142, 144.

Referring now to the body 112 of the helmet 100, FIG. 8 shows a front perspective view of the body 112. As noted above, the body 112 at least partially encapsulates some portions of the cage 110 and the strap hangers 142, 144. In some embodiments, the body 112 can be formed out of an expansive foam polymer (e.g., EPS foam). The body 112 can define a front end 172, a rear end 174, and opposing lateral ends 176, 178. The body 112 can also include a rim 180 situated around the periphery of the body 112, longitudinal ribs 182, and longitudinal openings 184 that are defined between adjacent longitudinal ribs 182, or the rim 180 and a longitudinal rib 182.

As shown in FIG. 8 , each of the longitudinal ribs 182 can generally extend between the rear end 174 and the front end 172 of the body 112. Furthermore, the longitudinal openings 184 can extend in a longitudinal direction between the rear end 174 of the body 112 and the front end 172 of the body 112. Each longitudinal opening 184 corresponds to and partially defines a respective vent 116 of the helmet 100 and, thus, each of the longitudinal openings 184 also receives the transverse beams 132 (e.g., each of the transverse beams 132 extends entirely through each of the longitudinal openings 184).

Referring back to FIGS. 1 and 7 , the body 112 at least partially encapsulates the cage 110. More specifically, the body 112 can fully encapsulate the cage 110 except for some portions of the transverse beams 132. As a more specific example, the rims 126, 128 are fully encapsulated by the body 112, and all the longitudinal beams 130 are fully encapsulated by the body 112. Thus, each of the longitudinal ribs 182 includes a respective encapsulated longitudinal beam 130. As illustrated, some portions of the transverse beams 132 are encapsulated by the body 112, while other portions are not encapsulated by the body 112 (e.g., do not include any portion of the body 112 surrounding the portion of the transverse beam 132). More specifically, in some embodiments, when assembled, a portion of one or more of the transverse beams 132 extends entirely through a respective vent 116 and is not encapsulated by the body 112 (e.g., does not include any portion of the body 112 surrounding it). Furthermore, as noted above, some portions of the strap hangers 142, 144 are encapsulated by or embedded within the body 112 while other portions, such as the lower opening 162 and the inner opening 164 of the strap receiver 152 are not encapsulated by the body 112, as shown in FIG. 7 .

Referring now to the shell 114 of the helmet 100, FIG. 9 shows a front perspective view of the shell 114. When assembled, the shell 114 is positioned on top of the body 112, and the shell 114 can be formed out of a different material as the body 112 and the cage 110 (e.g., a material that has a greater hardness). For example, the shell 114 can be formed out of a relatively rigid material (e.g., a plastic, such as polycarbonate). The shell 114 can define a front end 186, a rear end 188, and opposing lateral ends 190, 192. The shell 114 can include a rim 194 that extends around the periphery of the shell 114, a peripheral flange 196 that is coupled to (or integrally formed with) the rim 194 and which extends towards the center of the shell 114, longitudinal strips 198, and longitudinal openings 200 that are defined either between two adjacent longitudinal strips 198, or a longitudinal strip 198 and a portion of the rim 194. When assembled, each longitudinal strip 198 sits on top of and is coupled to a respective longitudinal rib 182 of the body 112. Additionally, as shown in FIG. 9 , the peripheral flange 196 can include apertures 202 (e.g., notches) to permit access to the lower openings 162 and/or the inner openings 164 of the strap hangers 142, 144.

In some embodiments, the cage 110 and the strap hangers 142, 144 can be together overmolded with the body 112, to deposit the body 112 about the cage 110 and the strap hangers 142, 144 so that portions of the cage 110 and the strap hangers 142, 144 are entirely encapsulated within the body 112. For example, the cage 110 and the strap hangers 142, 144 can be coupled together and placed in a mold (not shown) that has a surface that corresponds to the exterior surface of the body 112. In some cases, portions of the cage 110 and the strap hangers 142, 144 that are to be encapsulated with the material of the body 112 are placed between the interior surfaces of the mold, but not in contact with these surfaces of the mold, while portions of the cage 110 and the strap hangers 142, 144 that are not to be encapsulated with the material of the body 112 engage and contact the interior surfaces of the mold. In this way, when the expandable material (e.g., EPS foam) is injected into the mold, the expandable material will fill in to contact the interior surfaces of the mold thereby encapsulating portions of the cage 110 and the strap hangers 142, 144. However, because the portions of the cage 110 and the strap hangers 142, 144 are already in contact with interior surfaces of the mold, the expandable material is prevented from encapsulating this portion of the cage 110 and the strap hangers 142, 144. Regardless of how the cage 110, the strap hangers 142, 144, and the body 112 are coupled together, once these are assembled, the shell 114 is placed on top of and is coupled to the body 112. In some embodiments, the shell 114 of the helmet 100 can also be placed in the mold with the cage 110 and the strap hangers 142, 144 and molded with the body 112 at the same time as the cage 110 and the strap hangers 142, 144.

In light of the above, some embodiments can provide a helmet 100 including a cage 110 that both encircles one or more vents 116, 117 in order to provide structural support to the helmet 100 and receives strap hangers 142, 144 in order to transfer retention load from straps throughout the helmet 100 rather than at localized attachment areas. In such embodiments, the strap hangers 142, 144 can be coupled to the cage 110 and in-molded in the body 112 at the same time as the cage 110. This can improve manufacturing ease for strap systems, as well as improve accessibility, as the strap receivers 152 may be exposed outside of the body 112, permitting strap installation or replacement post-assembly. The strap hangers 142, 144 can also eliminate the need for additional non-structural components floating in the body 112 for receiving straps, which can improve body volume and EPS foam flow during assembly of the body 112.

It should be noted that the cage 110, the body 112, and/or the shell 114 can include different or other features without departing from the scope of the invention. For example, the strap hangers 142, 144 can be incorporated with cages of any of the helmets described in international application no. PCT/US2020/018956, filed Mar. 4, 2022, the entire contents of which is incorporated herein by reference.

It should further be noted that other structural support elements embedded in a body and that encircle vents of a helmet may be also used as load transfer elements for strap hangers. As but one example, FIGS. 10-15 illustrate another helmet 300 according to some embodiments. The helmet 300 can define a front end 302, a rear end 304, and lateral ends 306, 308. The helmet 300 can include a body 312 that defines one or more vents, including front vents 316 and rear vents 317 (shown in FIG. 14 ).

As shown in FIGS. 11, 13, and 15 , the helmet 300 can include one or more structural supports 310, including a front butterfly 318, a rear butterfly 320, and side supports 322, 324. Each of the supports 310, that is, the front butterfly 318, the rear butterfly 320, and the side supports 322, 324 can be encapsulated by the body 312 and encircle one or more vents 316, 317 of the helmet 300, similar to the cage 110 of the helmet 100. More specifically, the front butterfly 318 can be positioned at the front end 302 and can encircle some of the front vents 316. The side supports 322, 324 can be positioned near the front end 302 along the lateral ends 306, 308, respectively, and can encircle some of the front vents 316. The rear butterfly 320 can be positioned at the rear end 304 and can encircle the rear vents 317.

In some embodiments, the helmet 300 can include strap hangers, similar to the strap hangers 142, 144 of FIGS. 1-9 , coupled to one or more of the structural supports 310. For example, the helmet 300 can include front strap hangers, similar to the front strap hangers 142, coupled to the front butterfly 318 and/or the side supports 322, 324. Furthermore, the helmet 300 can include rear strap hangers, similar to the rear strap hangers 144, coupled to the rear butterfly 320. Thus, the structural supports 310 can both encircle one or more vents 316, 317 in order to provide structural support to the helmet 300 and receive the strap hangers (e.g., via a snap-on or press-fit engagement, as described above) in order to transfer retention load from straps throughout the helmet 300 rather than at localized attachment areas. The strap hangers can be coupled to the structural supports 310 and in-molded in the body 312 at the same time as the structural supports 310. As described above with respect to the cage 110, this can improve manufacturing ease for strap systems, as well as improve accessibility, and can also eliminate the need for additional non-structural components floating in the body for receiving straps, which can improve body volume and EPS foam flow during assembly of the body.
